Solids and mineralogy
Mineral type, particle size and nature, solids percentage, and feed variability.
Mineral processing and process water
Specialized chemistry for mineral processing plants and process water in mining
Reagent performance depends on the process where it is used: solids characteristics, water, dosage, mixing, hydraulics, equipment, and operating conditions. TREGA supplies chemical solutions and technical guidance for solid-liquid separation, clarification, and water management in mining operations.
Technical criteria
Mineral processing and process water interact, but they should be assessed separately
In thickening, clarification, filtration, and dewatering, solid-liquid separation depends on slurry characteristics, particle size and nature, solids concentration, mixing, dosage, hydraulics, and equipment.
The quality of recovered or recirculated water can affect the stability of other processes. Clarity, suspended solids, scaling, and water chemistry should be assessed according to the circuit and operating objective.
Critical variables
What should be reviewed before changing a chemical solution
Circuit response can change even when the reagent remains the same. The review should consider the complete process and the information available.
Water and circuit chemistry
Water quality and origin, pH, suspended solids, recirculation, and conditions that can affect other processes.
Mixing and hydraulics
Flow, mixing, shear, residence time, and hydraulic behavior at the treatment point.
Dosage and equipment
Product, dosage, preparation, addition point, feed conditions, and available equipment.
Two related contexts
Chemistry participates in different processes, and each requires its own technical criteria
The objective is not to transfer the same formulation from one point to another, but to understand which separation or water-management mechanism needs support.

Chemical solutions
Flocculants and coagulants as priority lines; other families according to the application
This page is not an exhaustive product catalog. Selection should start from the process objective and observed operating conditions.
Flocculants
Help form larger aggregates that can settle or separate more readily when the process condition requires it.
Coagulants
Can help destabilize fine particles and colloids as part of a separation approach defined for the treated stream.
Complementary solutions
Filter aids, antiscalants, defoamers, and other families only when the application and technical scope have been confirmed.
Technical guidance
Review of process information, available parameters, and observed behavior to guide selection or adjustment.
How TREGA participates
The process is reviewed before changing the chemical program
Understand the process
Locate the deviation point and the circuit’s technical objective.
Review variables
Analyze available information on solids, water, dosage, mixing, and operating conditions.
Select or adjust
Define product and parameters compatible with the identified problem.
Run controlled tests
Implement changes in a controlled way when the project scope allows it.
Follow up
Compare subsequent behavior and determine whether the target variable responded.
Transfer criteria
Provide guidance on preparation, handling, and application when appropriate for the project.
Performance diagnosis
When performance changes, increasing dosage does not necessarily correct the cause
System response can change because of variations in solids, mineralogy, water, flow, pH, mixing, shear, residence time, equipment, or feed conditions. Before changing a chemical program, it is useful to identify which variable changed and which part of the process is limiting the result.
Review a process conditionFrequently asked questions
Mineral processing and process water: criteria before adjusting chemistry
Direct answers about the scope of TREGA’s technical service line.
Which processes are covered by this TREGA technical line?
Solid-liquid separation, clarification, thickening, filtration, dewatering, and water management or recovery when the application and scope are defined.
Which chemical families are prioritized?
Flocculants and coagulants are TREGA’s declared priority lines. Other chemical families may be incorporated as complementary solutions according to the application.
Does dosage alone explain performance?
No. Results can change with solids, mineralogy, water, flow, pH, mixing, shear, residence time, equipment, and feed conditions.
What information helps guide a review?
Process type, treated stream, solids, water, current product and dosage, flow, pH, observed performance, and recent circuit changes.
Mineral processing and process water
Is chemical consumption increasing without a proportional process improvement?
Share the process point, observed condition, and available variables. The initial review should distinguish whether the limitation is in the reagent, dosage, or another circuit condition.
